CAR-UNLOADER.

SPBCIFICATION fo:ming part of Letters Patent No. 384,111, dated June 5,1888.

\ Application filed August 15, 1887. Serial No. 246,971.

To all whom it may concern:

Be it known that 1, HENRY M. BARNHART, of Marion, in the county ofMarion and State of Ohio, have invented certain new and usefulImprovements in Car Unloaders; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and usethe same.

My invention relates to improvements in carunloaders in which a plow andfender are employed,as heretofore, but with a connection between the twoparts'havingconsiderable vertical play. A lever attachment is bad withan adjustable poise mounted on the lever for partially counterbalancingor regulating the downward pressure of the plow, such pressure beingmade greater or less, according to the kind of material to beunloaded,to the end that, while the plow is always made to do its work,unnecessary wear or tearon thefioor of the car is avoided. By means ofthe lever attachmentand loose'connection aforesaid the unloader is madeto pass from one car to another without difficulty, although thedifferent cars may vary several inches in height.

My present invention is designed as an improvement on car unloader andballast-discharger patented October 14, 1884.,N0. 806, 688.

In the accompanying drawings, Figure l is a view in perspective. Fig. 2is a plan view. Fig. 8 is aview in perspective showinga modification oflever, hereinafter described. Fig. 4 is an enlarged section on line X Xof Fig. 1, and Fig. 5 is an enlarged elevation showing the end of theplow and attached mechanism for operating the same.

A represents a railway-car of the variety known as flat.

B is the plow,and O the fender. These parts are substantially the sameas heretofore used, except such modifications as hereinafter described.The rear arch-bar, C,of the fender has depending brackets cthat embraceloosely the forward end or cutter, B, of the plow. These brackets havevertical slots 0, and a bolt or pin, d, is made to pass through thecutter and to extend loosely through the slot 0, such bolt havingconsiderable vertical play-say eight or ten inches, more or less -in thesaid slot by means of which in passing over cars of difier- (No model.)

ent elevations the point of the plow may be elevatedordepressed from theplane that the fenderis traveling upon. BracketsD extend above thearch-bar C. These brackets embrace a lever, E, which latter is pivotedthereto at e. At e, a few inches in front of the fulcrum e, a link, F,is pivoted to the lever E, thelower end of the link being connected withthe extreme end of the plow-cutter. By means of this 1ever attachmentthe front end of the plow may be elevated or assisted in mounting a carof higher elevation, the fender of course having first mounted suchhigher car. A heavy poise or counter-balance, G,is mounted on the leverE. The poise is adjustable endwise of the lever and has a suitabledevice for securing it in its adjusted position, such securing devicebeing usually a set-screw, g.

The plow, in order to be able to cope with all kinds of material, mustbe of considerable weight, especially at the forward end. Otherwise withobstinate materialssuch, for instance, as dense mud-the point of theplow would belikely to ride upon the ballast instead weight of the plowaccording as the poise is moved rearward or'forward on the lever. Alever, E, of the return-bend variety shown in Fig. 3 may be used, inwhich case the poise may be moved over the fulcrum e, so as to beinoperative in its relation with the plow,or the poise may be movedforward over the link F, in which case the Weight of the poise would beadded to the weight of the plow, or the poise might be moved stillfarther forward, so that the pivot 0 would serve as a fulcrum for thelever, in which case a portion of the weightof the fender would be addedto the weight of the plow and poise. With this variety of le- .connectedwith and extending from the forward arch-bar, C of the fender, by whicharrangement the forward end of the fender is kept in line with thedraft-rod, while the rear end of the fender, by means of the bracket 0,keeps the forward end of the plow snbstantially in the central line'ofthe car, the rear end of the fender being kept in place by means of thecar-stakes a. Slay-rods hconnect the archbars 0 and G 'What I claimis- 1. In a car-unloadcr, the combination, with a plow and fender, thesaid parts having a vertical sliding connection with each other, of alever fulcrumed on the fender and loosely connected to the plow, wherebythe relative height of the plow to the fender may be regulated,substantially as set forth.

2. The combination, with a plow, a fender, and arch-bars connected withthe fender, of vertically-slotted brackets connectedyvith the reararchbar and made to embrace the forward end of the plow, a pin made topass through the cutter of the plow and into the slots of the bracket,substantially as set forth.

3. The combination, with a plow and a fender, of a lever pivoted to thefender, a link connecting the lever with the plow, whereby the frontportion of the plow may be elevated, substantially as set forth.

4. The combination, with a connected plow and fender, theformer havingvertical play, substantially asindicated, ofalever pivoted on the fenderand connected by a link with the cutter of the plow, substantially asset forth.

5. The combination, with a plow, a fender, and a lever, of a poise orcounterbalance mounted on the lever,substantially as set forth.

6. The combination, with a plow, a fender, and a lever, of a poisemounted on the lever, said poise being adjustable lengthwise of thelever, substantially as set forth.

7. The combination of a plow, a fender, a

lever, and apoise, substantially asindicated,

said lever having a return-bend, whereby the pois'e may he moved oneither side of the fulcrum of the lever, substantially as set forth.
